Urban Land Intensive Use Of The Evaluation Study

In recent years,as the urbanization speeding up in China, scale expansion of urban land use, occupation of arable land is very serious, at the same time, inefficient use of urban land extensive very prominent phenomenon. Therefore, the city improve the efficiency of land use, intensive use of urban land caused by the theoretical community, the planning sector and the Government attaches great importance to the Department. The central leadership has repeatedly saving and intensive utilization of land made important instructions. Hu Jintao clearly noted that the construction in accordance with the requirements of a conservation-minded society, and actively explore the establishment of land and resources management of the new mechanism, the full implementation of the measures of land management, conservation and intensive use of land; Premier Wen Jiabao's instructions, "put the stock of construction sites and promoting the intensive and economical use of land and are strictly essential aspect of land management ".If we say that the urban land intensive utilization resources for the purpose of economic and social development are to provide the protection of land resources, the urban land intensive utilization resources in real terms the level of evaluation is to improve the level of urban land intensive utilization resources as the core, through the intensive use of the level of the current situation assessment, analysis of cause the reasons for the extensive use of land and obstacles, and on this basis in order to explore the use of land resources in response to intensive way. In 1999, the Ministry of Land and Resources will be the urban land intensive utilization survey and evaluation of land resources survey as an important element, has selected the seven pilot cities (Fuzhou, Tianjin, Baotou, Changchun, Jinan, Yiwu, Nanjing) in town potential for urban land intensive utilization evaluation, land-intensive city began a prelude to the use of evaluation. One of, including the evaluation of content, evaluation methods, target systems and technology to build applications, including intensive use of urban land has become a quantitative evaluation of the core work of research. Application of quantitative methods to the extent of urban land use evaluation, a clear regional differences in land-use potential, not only urban land-use master plan of the important work of revising the content, but also the development of urban land use policy and management measures.In this paper, learn advanced theory, research methods and practice of investigation, based on fuzzy neural network set up a comprehensive evaluation model, and the Jinan, the city the potential of intensive utilization of land resources, made a tentative evaluation Discussion. The full text of the main from the following aspects are discussed: First of all, at home and abroad based on urban land intensive utilization study the theory of synthesis and a comparative study of the use of systems, the concept of scientific development, sustainable development and regional and other relevant theories, analysis of urban land intensive utilization the connotation of the use is proposed in this article on the intensive use of urban land re-recognize. Secondly, in the city to explore the impact of urban land intensive utilization, of factors, urban land intensive utilization in the city to determine the target system under the guidance of the principles and methods to determine the city's General Land Use Evaluation System. Third, determine the use of fuzzy math and the combination of neural network fuzzy neural network model of comprehensive evaluation of the intensive use of land resources in town to evaluate the level of research and evaluation process. Fourth, in Jinan as an example of intensive use of urban land empirical research. In reference to the principles of land evaluation methods and others on basic research, combined with the actual situation of Jinan and the collected data set of land use systems in Jinan specific evaluation target system, then use established based on fuzzy neural network model of the comprehensive evaluation of Jinan land-use intensive empirical analysis of the extent. Finally, the combined results of Jinan, the existing situation and future direction of the evaluation guide.
